Aokin 3D Printer POM Wheel Plastic Pulley Linear Bearing for Creality Ender 3, Ender 3 Pro, Ender 3 V2, CR-10, CR-10S Series 3D Printer, 10 Pcs

Picked up these to replace my Ender 3 wheels that were a year old. Direct replacement with no complaints. Worked as they should.

Replaced two of the originals that had developed a flat spot on the wheels (due to a failure on my part to adjust at the onset). There was a clunking sound as the wheels hit the flat spots. I replaced them easily with two of these news ones, and the sound went away. Did have to re-level the bed, but that was expected. Have been working well since the installation.

Finally pulley wheels that are round! Too many of the other ones Ive tried have been oblong and absolutely ruined my prints. With these, the first 3 I pulled out of the bag and installed were perfect and my printer is resurrected. I havent tried the rest yet, but the last batch I had from another brand were ALL bad. Do recommend.

I should have payed more for bearings, these things cut corners from the low quality grease to the inconsistent build quality to the sheer amount of friction in these even when warmed up. In the future I hope you can get in contact with your supplier and test the quality of a batch before someone else ends up halfway through a 3d printer rebuild only to find the old worn out bearings roll better than these. Sorry but now both our days are ruined.

My printers original wheels had developed flat spots from having the eccentric nuts over-tightened, and were seriously messing up layer height consistency and positioning accuracy. These replacements were an exact fit and immediately fixed my problem. I just used 6 for the Z axis and kept 4 as spares.

My z axis was getting wobbly on my ender 3 and these fixed the problem.

after eating up the stock wheels from bad adjustments I got the clear poly wheels. the clear wheels made a ton of noise and left residue on my rails no matter how i adjusted them so I went back to stock. new wheels and a silent board make my printer damn near a ghost while running now

Came in great shape and was able to swap out a few wheels easily on my Ender 3 V2

I had a bad set of wheels on a Ender 3 Pro heat bed and replaced them with these wheels. The bed is much smoother now and the prints come out well. The original wheels from Creality were loose from the start even after tightening the bolts. These are more stable. They seem good quality. I guess time will tell how well they hold up but for now they are good. .

Perfect fit. All 10 were in good condition with no defects detected. All I did was add a touch of liquid dry lube and they were very smooth. I will buy again if/when needed.
